SPECIFICATION forming part of Letters Patent No. 233,749, dated October 26, 1880.

Application filed February 24, 1880.

To all whom it may concern Be it known that I, WILLIAM E. GUMP, of Brooklyn, in the county of Kingsand State of New York, have invented a new and Improved Stereotype-Casting Box, of which the following is a specification.

The object of my invention is to secure adjustable gages to a casting-box, and do away with the separate frames between the lids of the box, so as to save time, labor, and cost.

Figure l is a plan of the box with a portion broken away the better to show other parts. Fig. 2 is an end elevation of the same.

Similar letters of reference indicate corresponding parts.

In the drawings, A represents the standard of the box; B B, the two vertical side posts; 0, the bottom of the box; D D, the movable gages, extended longitudinally along the bottom of the box and beveled on their inner lower edges, as shown at a, and adjusted and held in place by the screws E E, to the ends of which screws said gages D D are permanently attached.

F F are the vertically-pro] ectin g slotted ears or lugs, that are secured on either side of the box-bottom G, or may be cast with it; and in the slots 1) of these lugs or cars F F rest the screws E E, having on each of them two nuts, Gr Gr, one on each side of the lug or ear. By turning these nuts G Gthe gages D D may be approached toward or withdrawn from each other to regulate the operative width of the casting'box. and be locked securely in posi tion.

H is the box-cover, hinged in the ears I I,

as shown, and having on its rear end a pro jecting plate, K, that assists in supporting the box in an upright. position when said box is thrown back for a casting. the cover H is secured the core L, extending longitudinally along the center of said cover H. M is a handle by which to raise the said cover.

N is a cross-head, pivoted on one side of the side posts, B, and swinging transversely over the top of the box and clamping around the head of the opposite post, B, as shown.

0 is the hand-screw, passing down through the center of the cross-head N and resting upon the boss P, that rises from the center of the cover H. By means of this screw 0 the cover H is held firmly down upon the gages D D preparatory to a casting.

This casting-box, being pivoted on the transverse bar or rod Q, in the standard A, is tilted backward when a casting is to be made, so as to rest on the rear end of the plate K, whereby it is then supported in position. When in, a horizontal position the front of said box rests on the transverse bar S.

Having thus described my invention, I claim as new and desire to secure by Letters Patent A casting-box having vertically-projecting lugs attached to the sides of thebottom piece, and slotted to form screw-supports, in combination with side gages provided with permanently-attached screws, on which work adjusting-nuts, as described.
